With the development of network technology, changes in the way audiences receive information have determined that in the 3G era, various wireless terminals will become more intelligent and various digital music applications will become more diverse. Digital music has become the most dynamic growth point in the online culture industry. Google launches digital music store business. It's the first time Google has sold songs on its Android online store, which offers apps, movies and e-books, as it seeks to compete with Apple Inc's iTunes store. Although Internet companies have launched music store businesses one after another, and the digital music situation seems to be prosperous, digital music still faces great difficulties on the road to development, and piracy is the biggest obstacle. More than 90% of the digital music content on the Internet is unauthorized. When piracy is rampant, it has caused a problem of high digital music user base but inability to generate higher income. Too much pirated content has caused huge losses to genuine music. Not long ago, Baidu signed a contract with the Musical Writers Association and will pay songwriters according to the number of online plays and downloads by users. In 2010, the Ministry of Culture shut down more than 300 websites that engaged in online music operations without approval. These moves make industry insiders optimistic about the future of the digital music industry. The capital market has also begun to pay more and more attention to China's digital music market. Experts analyze that with the improvement of the industrial environment and the strengthening supervision of the digital music market by network authorities, the market environment will be greatly improved in the near future. Perhaps in this way, the development speed of digital music will be even more rapid.
